Nope, I got that log, and it shows that pretty often the connection
open from Linux to OS/2 fails with "Connection timed out".

Me neither (exactly) -- example of failed delivery did not
fail at the SMTP transport, thus it must have failed once
the GIGO/2 started to process it.
It is pretty easy to make sure that all email goes via
si-star1 in its way to si-star2; at the DNS:
si-star2: IN A ....
IN MX 10 si-star1
Now all MX-respecting systems (all should..) notice that,
and send to si-star1. The "fun" is that you can configure
the ZMailer to reserve a special queue for si-star2, and
thus ensure that it never runs more than one session to it.
At the scheduler.conf, add a definition:
smtp/si-star2.si-star.com
with the same stuff as the smtp/* has.
